混沌优化在船舶码头系泊缆绳张力计算中的应用(英文)

Application of Chaos Optimization Algorithm in Calculating the Moored Ship Cable Tension

系泊船舶缆绳张力的模型实验研究和理论计算对于缆绳的选取、系泊设备的设计、系泊方式及预紧力的确定,以及船级社规范的制订都有着重要的指导意义. 国内对码头系泊的研究相对较少,且主要依赖于模型实验. 文中对小波浪水域码头系泊船舶缆绳张力的计算建立了数学模型,并用混沌优化的方法对非线性系泊方程组进行了求解,其结果与实验结果对比有较好的一致性.

Model experimental research and theoretical calculations of being moored ship’s cable tension have important guide significance to cable selection,mooring equipment design,mooring means and the determination of preload,as well the formulation of classification society standard. There is less research of pier mooring relatively in domestic,and mainly depends on the model test. This paper established a mathematical model to calculate the mooring ship’s cable tension,which is subjected to small water waves,and then solved the nonlinear moorage equations by means of chaos optimization method. After comparing the calculated results with the ones obtained from the experiment, they are found to be in good agreement.
